eileencodes 350d0aa023 [ruby/error_highlight] Support nodes in `spot`
Fixes a bug where `spot` was using the wrong local variable.

We want to use error highlight with code that has been eval'd,
specifically ERB templates. We can recover the compiled source code of
the ERB template but we need an API to pass the node into error
highlight's `spot`.

Required Ruby PR: https://github.com/ruby/ruby/pull/6593

What is Ruby?

Ruby is an interpreted object-oriented programming language often used for web development. It also offers many scripting features to process plain text and serialized files, or manage system tasks. It is simple, straightforward, and extensible.

Features of Ruby

  • Simple Syntax
  • Normal Object-oriented Features (e.g. class, method calls)
  • Advanced Object-oriented Features (e.g. mix-in, singleton-method)
  • Operator Overloading
  • Exception Handling
  • Iterators and Closures
  • Garbage Collection
  • Dynamic Loading of Object Files (on some architectures)
  • Highly Portable (works on many Unix-like/POSIX compatible platforms as well as Windows, macOS, etc.) cf. https://github.com/ruby/ruby/blob/master/doc/maintainers.rdoc#label-Platform+Maintainers
